Introducing RLTool Net 3.1
RLTool
is a Windows -supported program for planning Radio-Relay Hops, Circuits
and Networks. The program runs on an Windows 98, NT, 2000 and XP.
It includes:
The program is transparent with respect to radio-frequency ranges, capacities, transmission hierarchies (PDH or SDH), type of equipment and manufacturers. The network to be designed may include different capacities and radio frequency (r.f.) ranges. RLTool facilitates the use of passive repeaters; it provides for the planning and design of individual hops as well as complete networks. Cable lines can be included in order to predict the overall performance and unavailability of mixed-media circuits and connections.
The formulae used in the program are based on the relevant ITU recommendations (if such exist), they are described in detail in K&K Engineering’s Technical Paper KKE 5201/5: Performance and unavailability - Principles and formulae. For a more profound understanding of the methods and formulae utilized in this program, reference should be made to K&K Engineering’s Monographs: Planning and engineering, Performance and availability and Frequency planning.
The number of hops and circuits (or links), which can be handled by the program, as well as the number of hops included in a circuit, are only limited by the capacity of the PC used. The results are presented as tables, and for the profile, as profile charts. For a better overview, the radio-relay network and its associated hops, as well as the various links established over this network, and the harmful interference paths utilized are shown as geographical network layout charts.
The tables and the charts are presented on the screen as different views, which also can be printed on paper. All user data and results, are stored in a project file.
The GUI is standard Windows menus and dialogs. The user data are inserted via dialogs windows or from data files respectively. All user data are validated when entered, and the physical unit is appended where applicable. The input data for the equipment - radios, antennas, feeders - are stored in separate files. These files can be produced from text files, or pre-compiled sets of equipment files which can be acquired from K&K Engineering. The input data from earlier planned networks, stored in data files, can be loaded at any later time.
A decisive parameter for the calculation of multipath fading and distortion probability is the so called terrain roughness. This parameter is defined as the standard deviation of the terrain altitude samples (in meters) within an 110x110 sqkm area around the centre point of the radio hop. ITU-R recommends to obtain the sample data from eg the Globe gtopo30 data, which give the sample data with a resolution of 30”. The data files are available on Internet under address
http://www1.gsi.go.jp/geowww/globalmap-gsi/gtopo30/gtopo30.html. The gtopo30 data cover the whole Globe, but are split up into 33 segments, each covering its part of the Globe. It is, thus, sufficient to download only that segments which covers the area of your interest. However, for your convenience, the gtopo30 data are included in the delivery CD.

RLTool
is a Windows -supported program for planning Radio-Relay Hops, Circuits
and Networks. The program runs on an Windows 98, NT, 2000 and XP. It includes:
- element PRO for the determination of antenna heights, and for the analysis of path profiles, both with respect to path clearance and ground reflections
- element PAC for the prediction of hop and circuit performance and unavailability (including hardware unavailability) - and
- element FRPLAN for frequency planning and interference prediction.
The program is transparent with respect to radio-frequency ranges, capacities, transmission hierarchies (PDH or SDH), type of equipment and manufacturers. The network to be designed may include different capacities and radio frequency (r.f.) ranges.
